男主与老人的真是关系是怎么样的？

很好奇男主与老人的真是关系是怎么样的？

律师调查发现老人名下并没有男主当园丁的登记 但是男主却一直生活在老人家里

从女仆的话当中可以得知是她照顾男主

女仆原话“I raised that boy since he was the size of a piss ant”

“...and I'll say right now he never learned to read and write.”

“He had no brains at all.”“Stuffed with rice pudding between the ears.”

"Short-changed by the Lord and dumb as a jackass.

那么男主究竟为什么在老人家一直生活的呢？
